A new inorganic-organic hybrid, [Zn(phen)2(ppy)][{Zn(phen)2}{Zn(phen)2(H2O)}{P2W18O62}] · 2H2O (phen = 1,10'-phenanthroline, ppy = 2-(5-phenylpyridin-2-yl)pyridine) (1), by using pre-prepared Wells-Dawson salt α-K6P2W18O62 · 15H2O as precursor, has been synthesized under hydrothermal conditions. Compound 1 was characterized by single-crystal X-ray diffraction, elemental analyses, IR spectrum and cyclic voltammetry. Yellow crystals crystallized in the monoclinic space group P2 (1)/c with a = 16.2450(11) Å, b = 17.0918(11) Å, c = 43.640(3) Å, β = 92.0060(10)°, V = 12109.4(14) Å3, Z = 4. The title compound represents a novel zero-dimensional structure based on bisupporting Wells-Dawson POM: one terminal oxygen atom located in the “belt” site and another located in the “cap” site of the same hemisphere of the polyanion are coordinated by Zn2+ cations. Compound 1 also contains the isolated secondary metal complex [Zn(phen)2(ppy)]2+ with two different organic ligands phen and ppy. |
